Description

ISD1820 is a small Voice Recorder and Playback module that can do the multi-segment recording. The user can achieve a high quality of recording (for 8 to 20secs) for each application with the adjustment of the on-board resistor. This Voice Recorder/Playback module is designed with embedded-Flash memory, which can hold data for up to 100 years and erase/record the life cycle up to 100,000.

This ISD1820 Voice Recorder/Playback Module reproduces high-quality, natural voice and audio from the recorded audio by Mic or driven through Microcontroller. Because of its dual operation mode (Standalone and Microcontroller driven), we can easily use this as per requirement and with a slight change of the onboard resistor, we can get flexibility in the sampling frequency of the recording duration & quality.
